- Process For Beneficiation Of Copper Ore
Abstract The possibilities of extracting valuable components and producing selective good-quality concentrates from hard-to-beneficiate crude ores are considered for the disseminated copper–nickel ores from the Norilsk district. The stated aim is achieved by a combined technology including beneficiation and hydrometallurgical processes. …

In recent years, the demand for strategic metals like cobalt, nickel, and copper has greatly increased. Africa has attracted the attention of the world due to its rich Cu and Co resources, and its Cu-Co ore can be mainly divided into sulfide, oxide, and mixed. 1 Among those stages, acid leaching of valuable minerals from the ore is the key …
